I would recommend avoiding dealing with 'Makefile.in' directly, unless you are interested (or troubleshooting) the nitty-gritty details of GNU automake. It is automake that reads /testsuite/local.mk and generates (lots of) targets that eventually help 'make check' "just work". In ./testsuite/local.mk every item listed to the TESTS variable will become a test when running 'make check' - regardless of whether it is a recursive build system or not. > I see the target "check", it's rule was : $(MAKE) $(AM_MAKEFLAGS) check-recursive, but the check-recursive was a member of RECURSIVE_TARGETS, how it find and build the tests? This is part of automake's complicated system. I do not claim to be an automake expert, but I can offer some pointers: If you run "make --just-print check-recursive" you'll see: $ make --just-print check-recursive ... target=`echo check-recursive | sed s/-recursive//`; ... This command is part of a target definition of "$(am__recursive_targets)", which expands to multiple targets (including 'check-recursive'). This variable is created with: am__recursive_targets = \ $(RECURSIVE_TARGETS) \ $(RECURSIVE_CLEAN_TARGETS) \ $(am__extra_recursive_targets) And 'RECURSIVE_TARGETS' iteslf contains 'check-recursive': RECURSIVE_TARGETS = all-recursive check-recursive [...] Again, I wouldn't recommend going down that path unless you are debugging automake issues. Running 'make check' should build programs required for testing (there are only two small C programs needed for the tests), and then executes the actual tests (which are shell scripts and do not require any building). If there is a problem in the tests (e.g. a test that does not execute correctly), please report it - it's a bug. Two known bugs regarding tests are running tests under windows, and enabling the old regex extended tests - currently there is no fix for this issues (patches welcomed). If you'd like to add tests - please add them to ./testsuite/local.mk, not to Makefile.in directly. Hope this helps, regards, - assaf
